Stable Particle: Create particle without particle system [Urgent]

I want to know how to create a stable particle. Stables particles are particles that doesn’t move and doesn’t disappear. Unlike particle system, stable particle is alone, it’s not a group. Adding a script that make plane look at the player or use particle system eat CPU. Any idea?

I need an awnser fast, also, if you need more information, tell me in the comment.

try creating a game object and adding it as a child to your “plane” or desired gameobject
